Definitions

  • the present invention relates to sliding surfaces of sports equipment and, more particularly to attachments that enhance sliding characteristics of said equipment, most particularly for wheeled sports equipment such as skateboards and roller skates.
  • the skateboard 10 comprises a platform ("deck") 12 for standing on, and two pairs of wheels 16 attached to the bottom 13b of the deck 12.
  • the two wheels 16 in each pair are mounted on an axle 24 protruding from the two sides of a "truck” 22 that is attached to the deck 12.
  • Bearings 17 between the wheel and the axle e.g., ball bearings are used to minimize frictional drag on the wheel.
  • the truck 22 is whatever structure rollingly attaches one or more wheels 16 to the rest of the equipment, i.e., the deck 12.
  • the truck 22 includes provision for tilting and/or rotating the axle 24 relative to the deck 12 to enable the skateboard 10 to turn.
  • the deck 12 has a top 13a and bottom surface (face) 13b, side edges, a nose (in front) 14a and a tail (in back) 14b.
  • the deck's nose 14a and tail 14b are virtually the same shape and size such that the board 10 can be ridden in either direction.
  • Virtually the entire bottom surface 13b and uncovered portions of the top surface 13a of the deck 12 are usually embellished with colorful graphics 20 according to the taste of the skater.
  • a skater rides along a raised surface (e.g., rail 100, wall 102) by positioning the skateboard 10 so that a portion (e.g., nose 14a) of the board's deck (generally the bottom face 13b but could also be an edge or even the top face 13 a) slides along the raised surface 100, 102 instead of rolling on the wheels 16.
  • a portion e.g., nose 14a
  • the board's deck generally the bottom face 13b but could also be an edge or even the top face 13 a
  • the deck 12 rubs against metal bars, rails, benches, concrete barriers, stone curbs, right angle wall edges, etc.
  • skaters may use wax or some other lubricant on the deck 12, on the raised surface (e.g., 102) or on both for reducing friction to enhance the gliding effect.
  • the deck 12 With increased wear, the deck 12 itself can be damaged.
  • a board 10 with a new coat of lubricant has a different slipperiness ("slide feel") than one where the lubricant is wearing off, and the slide feel continues to change when the lubricant is gone and the board 10 is sliding on a coat of varnish or paint or graphic decal.
  • skateboards 10 are typically replaced rather frequently, particularly when used in competition. And the modern, high tech skateboard can be very expensive.
  • Grinding is another skateboarding trick that is very hard on the equipment (see Figure 4). Like sliding, grinding is when the skater rides along a raised surface (e.g., a rail 100) by positioning the skateboard 10 so that either or both of the trucks 22 slide along the raised surface instead of rolling on the wheels 16. Again, reduced friction and minimized wear damage are highly desirable.
  • the terms “grinding” and “sliding” are sometimes used interchangeably, particularly by those less familiar with the sport, such that either term can be considered a generic term for the action of riding along a surface on any part of the skateboard 10 other than the wheels 16.
  • skateboards 10 Another demand on skateboards 10 is a result of jumping (doing an "ollie"). Not only must the deck 12 resist breaking or delaminating when the skater on the skateboard drops down from an elevation to a lower level, but the deck 12 must also be springy so that the deck 12 can be impacted for bending it downward and then unweighted such that it springs upward to rise with the skater when he/she jumps. It is highly desirable to both improve breakage/delamination resistance and to increase the springiness ("pop") of the deck 12.
  • skateboards 10 A common problem with skateboards 10 when they are used for jumps or hard turns is "wheel bite", illustrated at location 200 in Figure 5. This occurs when the deck 12 is tilted so much relative to the truck 22 that the wheel 16 on one side of the truck 22 rubs against the bottom 13b of the deck (e.g., at location 200). The increased friction on only one portion of the board 10 can cause slowing at best, and falls in worst cases. Serious skaters generally customize their skateboards 10 to meet their own performance needs and preferences, as well as their personal tastes in appearance.
  • the first step is to select a deck 12. Because there are at least ten different size/shape variations and more than fifty factory applied graphics and colors, very few stores will have a stock of every possible combination of size, shape, color and graphic design.
  • the deck 12 is generally ordered from a catalog rather than purchased off a store shelf.
  • a "grip tape" material 18 is applied (usually self-adhered) to at least a portion of the top 13a of the deck to provide a non-slip surface for the skater to stand on.
  • the grip tape 18 may be already applied by the deck 12 manufacturer to fit in with the graphics, or else it can be done when the skateboard 10 is being assembled.
  • the trucks 22 and wheels 16 must also be selected from a range of sizes, manufacturers, materials, performance and quality levels.
  • skateboard components can be ordered from a catalog to be assembled by the catalog company or can be obtained from possibly multiple sources and then assembled by the skater or by a retail assembler of made-to-order skateboards 10.
  • Screw holes and screws in the deck 12 affect both the strength and the pop of the deck 12, therefore it is desirable to minimize the number and size of screws in screw holes drilled into the deck 12. It is also desirable to minimize the weight of the skateboard 10.
  • Typical skateboard materials include painted laminated wood for the deck 12 (e.g., 7 layers of hardwood glued together), and aluminum, steel or various alloys for the trucks 22. Besides wax and lubricant, it is known to apply a varnish-like coating of polyurethane on the deck 12 as a protective and somewhat slippery layer (clear so that graphics 20 under the coating are visible).
  • the grip tape 18 is a sheet or ribbon of material that has a non-slip surface (e.g., sandpaper-like) on one side and an adhesive backing on the reverse side. It can be cut to a desired size and shape and adhered to the top of a deck 12 by a skater or by a retail assembler.
  • the grip tape 18 is a "post production” component, i.e., a component that is applied after production of a completed skateboard deck - after lamination, cutting, shaping and surface finishing (e.g., paint and/or varnish).
  • Graphics 20 may be applied as part of the deck production process, but it is more efficient to apply them post production upon receiving an order for a given deck/graphic combination.
  • skateboards Various additional components are or have been available for post production customizing of skateboards 10, many of them designed to protect parts of the board 10 and/or to increase the slipperiness of the deck bottom 13b.
  • "Rails” or “rib bones” are narrow plastic strips that are attached under the deck 12 along the edges.
  • a "jaw bone” is a plastic strip shaped in an arc to attach around the bottom of the nose 14a
  • a "tail bone” or “tail guard” is a strip that can be attached under the back edge of the tail 14b. All of these "bones” have fallen out of favor because of various disadvantages: they add to the weight, they are attached with screws or nails, and they are relatively thick, e.g., as much as a half inch thick.
  • An example of a tail guard is the skid pad (39) disclosed in USP 6,074,271 (Derrah; 2000). Derrah's skid pad is made of UHMW (ultra high molecular weight) plastic and appears to be fairly thick as illustrated in Derrah's Figs 1 and 2.
  • the prior art also includes some devices (“copers”) for increasing slipperiness and wear resistance of the skateboard trucks 22 while grinding. Again there are problems that have made the devices unpopular: generally they wear out quickly, and are tedious to replace.
  • USP 6,648,372 (Ojeda; 2003) discloses a skateboard truck guard comprising a sheet of material that is formed into a guard body (20) that is appropriately shaped for wrapping around the axle- holding "hanger" portion of the truck.
  • the guard body is preferably made of a durable material such as alloy, polyurethane, or fiberglass for providing a predetermined friction, and is securely attached to the truck by fastening elements (30) such as zip-ties, loop-shaped clips or durable wires.
  • USP 6,945,542 discloses a skateboard track shield comprising a discrete sheet of material (preferably UHMW polyethylene) that has a smooth, low- friction surface and is formed to encircle portions of the track assembly so as to hold the sheet of material in a fixed position underlying and covering the lower surface of the truck with the smooth, low-friction surface directed downwardly.
  • the shield (15) has a first hole (54) adjacent one end of the truck shield body positioned to encircle the pivot strut (25) and two additional holes (51, 52) adjacent an opposite end of the shield body positioned to encircle the mounting post (40).
  • the truck assembly must be disassembled and reassembled in order to attach Stewart's shield.
  • USP 6,648,345 discloses an anti-wear strip equipped wheel seat of skateboard.
  • the strip (12) is made of a "wear resistant material” and appears to be some type of metal that covers the bottom of the truck (11) to provide an anti-wear face.
  • the strip is U-shaped such that "end edges are embedded along with the axle (13) in the main body" of the truck. Presumably the truck must be replaced when the embedded anti-wear strip wears out.
  • Tricks such as sliding and grinding that were initially developed by skateboarders have been adapted for use with related sports equipment such as scooters, rollerblades, roller skates, inline skates, and trick bikes.
  • related sports equipment such as scooters, rollerblades, roller skates, inline skates, and trick bikes.
  • Stewart '542 mentions that his truck shield can protect surfaces between wheels on in-line skates and the like.
  • trick bikes have rod-like pegs extending laterally outward from the bike sides (e.g., outward from a wheel axle). Although the pegs are intended for standing on by the bike rider, the bike can also be caused to slide or grind by riding the bike on a peg sliding along a surface instead of riding on a rolling wheel.
  • skateboard components that enhance performance properties including sliding, grinding, weight reduction, and wear/damage protection.
  • inventive components be suitable for simple post-production customizing of skateboards.
  • a performance enhancing attachment for sports equipment comprising: a high performance plastic layer; and an adhesive on one surface of the plastic layer for adhering the plastic to the equipment.
  • the adhesive is an aggressive, high-tack adhesive; and the adhesive is resilient.
  • the plastic is UHMW plastic.
  • the plastic and the adhesive are substantially transparent.
  • the plastic is 0.005 to 0.030 inch (0.13-0.76 mm) thick, and more preferably is about 0.020 inch (0.51 mm) thick.
  • the plastic layer is suitable for adhering to the entire bottom surface of a skateboard deck.
  • the plastic layer incorporates graphics.
  • a method for enhancing sliding performance of sports equipment surfaces comprising the steps of providing a wear resistant, low friction material in the form of a relatively thin and flexible sheet; and supplying a resilient, aggressive, high-tack adhesive layer on a surface of the sheet material.

  • plastic in industrial applications has provided many benefits throughout recent years. Numerous industrial components have been replaced with, or have been improved through the use of, "engineered polymers" due to the identification and implementation of their unique characteristics such as wear resistance, low coefficient of friction, and endurance in harsh environments. Plastics can be used in places that traditional materials such as metal or wood simply can not perform, or deteriorate quickly in use. Catastrophic failures and undesirable operating behaviors can be minimized or even eliminated in many applications through the use of appropriate plastics.
  • Plastics provide reductions in friction that can significantly enhance performance, increase life and maintain high levels of performance without the need for service or maintenance over the life of the product, for example a wheel bearing 17.
  • plastics/polymers such as Acetals (Delrin), Acrylic, CPVC, EVA, FEP Fluoropolymers, Fiberglass-FRP, Garolite®, G10/FR4 Phenolics, HDPE, HIPS-Polystyrene, Kevlar, LDPE, LLDPE-Linear Low, MDPE, Noryl®, Nylon, Nylatron®, PBT, PEEK, PETG, PFA-Fluropolymer, Polycarbonate, Polyimide, Polypropylene, Polystyrene, Polysulfone/ Ultem, Polyurethane-TPU, PTFE, PVC, PVDF, Santoprene®, Teflon®, Torlon®, Tygon®, UHMW, UHMWPE, Ultem®, PEI, Versilic®, Zelux®, and others can provide enhancements in the current offerings for scooter, skate, and skateboard bearings 17, skid plates, and graphics protectors.
  • Replacing ball bearings 17 in skate wheels 16, 34 with solid plastic bearings 17 can provide performance advantages as well as eliminate all of the above disadvantages found in the current steel or ceramic ball bearing 17 offerings. These advantages may take many forms that utilize polymers such as multipart plastic bearings 17, multipart plastic and metal bearings 17, and polymer coatings on metal, plastic, or other materials that are made to act as a bearing 17 and utilize the advantageous properties of plastic for this application.
  • the entire wheel 16, 34 is made of a selected plastic that has no bearings 17 installed. In this case, the wheel 16, 34 is the bearing 17.
  • the wheel 16, 34 can have other materials molded to or affixed to it for appearance or added performance.
  • Skateboards 10 are embellished with colorful graphics 20; however, as described above with reference to Figures 2 and 3, even when using wax or some other lubricant, sliding tricks quickly cause the graphics 20 on the sliding surface (e.g., bottom 13b) of the boards 12 to be damaged or completely worn away.
  • the present invention involves placing a relatively thin (e.g., 0.005-0.100 inch, 0.13-2.5 mm thick) sheet 42 of plastic on the bottom of the board, thereby significantly enhancing the glide effect without the use of additional lubricants, and also protecting the underlying graphics 20, e.g., with the use of substantially transparent ("clear") plastic sheet 42.
  • substantially transparent or clear means that the graphics 20 can be seen through the material, therefore the terms encompass translucent material that is thin enough to allow satisfactory viewing of the graphics 20.
  • the invention also involves providing the thin plastic, sheet material 42 with a pre-applied coating of adhesive that enables self-adherence of the plastic 42 to surfaces such as the bottom 13b of the deck 12.
  • the adhesive is preferably an aggressive, high tack adhesive, most preferably one that is substantially clear in thin layers.
  • An off-the-shelf example of a suitable adhesive is the "superstick" rubber based adhesive used on Avery #8345 double coated polyester tape (A very Dennison; Painesville, Ohio, USA). It will be seen that a resilient adhesive such as a rubber based one provides some advantages.
  • the plastic 42 can be supplied in various convenient forms such as, for example, large sheets (e.g., the size of a skateboard deck 12), pre-cut pieces, and cut-to length strips.
  • Figure 6 A shows material 40 as supplied in a convenient roll.
  • the plastic is supplied as a multilayer material 40 that is shown magnified in Figure 6B, which comprises a layer of the plastic 42 (e.g., 0.020 inch, 0.51 mm thick), a layer of adhesive 44 (e.g., 0.005 inch, 0.13 mm thick), and a removable layer of liner paper 46 (e.g., 0.012 inch, 0..30 mm thick).
  • a piece of plastic sheet e.g., a nose-covering piece 42a
  • a piece of plastic sheet can be self-adhered to the bottom surface 13b of the deck 12, protectively covering the nose graphic 20a, and enhancing the sliding characteristics of the entire nose portion 14a of the board 10 from the truck 22 forward.
  • the plastic 42 that extends beyond the edges of the deck 12 can be easily trimmed off, for example with a knife, or for example, the material 40 can be marked with a pencil on the liner paper 46 and cut to shape before the liner paper 46 is removed.
  • the material 40 can be provided to the user as a pre-cut piece.
  • the nose- covering piece 42a will protect the deck 12 and graphic 20a when the board 10 is used for sliding along a wall 102 as shown in Figure 2.
  • the plastic 42 also greatly enhances lubrication to enable much longer slides, and furthermore produces a consistent amount of lubrication so that repeated slides will be predictably consistent. This is because the high density plastic is so resistant to wear that it changes very little over the course of many slides. Finally, if a clear plastic and adhesive are used as preferred, then the protected graphic 20a is still visible.
  • plastic sheet material 42 can be applied to the bottom 13b along the edge of the deck 12 (e.g., a 1 inch, 25 mm wide "tape"). If applied along both edges, then the plastic strip(s) 42c will protect the board during slides anywhere on the bottom surface 13b of the deck 12, e.g., in the middle between trucks 22 as shown in Figure 3. Furthermore, since the plastic strip 42c is located between the wheels 16 and the deck 12, the plastic 42 will lubricate any rubbing contact (e.g., at location 200 in Figure 5) thereby minimizing "wheel bite”. In another example, small plastic patches 42b can be applied only where needed to minimize "wheel bite”.
  • Figure 7B illustrates another example which is a preferred embodiment, wherein the plastic 42 is adhered to the entire bottom surface 13b of the deck 12 and the wheel trucks 22 are then screw attached to the deck 12 with the plastic 42 sandwiched between the bottom surface 13b and the truck 22.
  • a clear plastic 42 with a clear (transparent) adhesive 44 is used and the graphics 20 are already applied to the bottom surface 13b.
  • the adhesive 44 is a resilient composition
  • the plastic sheet 42 is UHMW plastic that is 0.005-0.030 inch (0.13-0.76 mm) thick, most preferably about 0.020 inch (0.51 mm) thick.
  • a graphic 20 could even have a thin layer of electroluminescent material in it to add light-up abilities to the graphic 20 and the board 10.
  • the trucks 22 are used for grinding.
  • high performance plastic 42 both protects the deck 12 and enhances the deck's sliding properties, so the invention can be used to protect the truck 22 and enhance the truck's grinding properties.
  • a piece of the plastic 42 is pre-cut to a suitable size, the liner paper (46, not shown) is peeled off to expose the adhesive 44, and the plastic 42 is then self-adhered to the bottom, axle-holding, "hanger" portion 23 of the truck 22.
  • the plastic 42 is relatively thin, and since the adhesive 44 is an aggressive, high tack adhesive, the plastic 42 can be quickly and easily adhered to the bottom 23 of the truck 22, even if non-linear, complex shapes are involved.
  • the plastic sheet 42 can be adhered to a complex surface in a way that might create folds, but the folds are easily trimmed with, for example, a razor blade.
  • the addition of the inventive self-adhering plastic 42 on the truck 22 provides a more desirable sliding ("grinding") performance - enabling longer grinds and more consistent or repeatable grinding - as well as protecting the truck 22 with a lower cost replacement part (the plastic 42) which is easily and quickly installed and replaced.
  • An alternative embodiment of the inventive use of high performance plastic is a truck hanger 23 that is made entirely of a plastic that demonstrates the best properties for grinding, wear resistance, and aesthetics.
  • high performance plastic e.g., UHMW
  • a criterion being that a surface of the equipment not originally intended for such use can be used for sliding on another surface, thereby adding new dimensions to the use of the sports equipment, particularly if friction and wear can be significantly reduced.
  • a secondary criterion is a desire for a surface enhancement that can easily and creatively be implemented by an end user of the sports equipment.
  • FIG. 9 A first example of invention use on a related item of sports equipment is shown in Figure 9, wherein the sole 32 (i.e., the bottom surface) of a skate boot 30 can be covered with a layer of self-adhered plastic 42.
  • One side of the sole 32 is shown covered by a rectangular piece of the plastic 42b, which can be trimmed to look like the custom shaped piece of plastic 42a shown on the other side of the sole 32.
  • a set of in-line skate wheels 34 is mounted between two support rails 36 that are attached to the in-line skate boot sole 32.
  • the rails 36 are analogous to the truck 22 on a skateboard 10, therefore plastic strips 42c, 42d applied across the rails/truck 36 between wheels 34 will enhance "grinding" performance on the inline skate 30.
  • Figures 10A- 1OB show a common shoe 50 that has been enhanced by adhering the plastic 42 to the arched (recessed) portion 54 of the shoe's sole 52.
  • the plastic 42 is also adhered to the leading edge of the heel 56, thereby providing a groove that is very slippery while not affecting the ground-contacting portion of the sole 52.
  • the shoe wearer can walk normally without slipping, but can easily slide sideways on a raised surface of suitable width such as, for example, a rail 100.
  • Figures 1 IA-I IB show a stunt bike 60 (e.g., a BMX bike) that has been enhanced by adhering the plastic 42 to at least a portion of the surface of a peg 62 that extends from the bike frame, e.g., at the center of the wheel 64.
  • the peg 62 is generally provided on such bikes so that the rider has another place to stand besides the pedals.
  • adhering the plastic 42 to only the bottom portion of the peg 62 the rider still has a non-slip surface on which to place his foot 104.
  • High performance plastics provide many advantages over metal or lubricant coatings for improved sliding, grinding, wear protection and weight reduction. They enhance the everyday skater's ability and enjoyment, and they add a competitive advantage to the professional's arsenal.

L'adhésif (44) est, de préférence, un adhésif agressif, à adhérence instantanée élevée et résilient. Le plastique (42) est, de préférence, un plastique UHMW. L'utilisation d'un plastique (42) et d'un adhésif (44) sensiblement transparents permet de laisser visibles des graphiques recouverts d'une couche de protection de la fixation. Une couche de plastique (42) relativement mince et flexible permet une utilisation par un utilisateur final dans une large gamme d'améliorations d'équipements créatives. Une utilisation particulièrement avantageuse consiste à protéger la surface inférieure (13b) d'une planche à roulettes (12) et/ou le fond (23) d'un chariot de roues (22).
